DW Spectrum User Manual
When DW Spectrum discovers a camera, it captures the manufacturer's preset image quality settings and streaming configuration, then adjusts these settings to optimize the device for the DW Spectrum Site. Manufacturer settings can also be adjusted manually, for example FPS, quality, and bitrate when a recording schedule is defined, or stream settings for a variety of reasons (see "Dual Stream Processing").
However, in some cases, it may be preferable to keep the native settings. For instance, you may want to maintain pre-existing FPS, bitrate, and resolution settings when connecting DW Spectrum to another VMS Site. Or, on occasion the ONVIF implementation for a given camera diverges from standard ONVIF enough to make it preferable, or even necessary, to keep the manufacturer settings.
It is possible to prevent the automatic optimization that DW Spectrum performs and use native stream and profile settings instead.
To disable automatic optimization for a single camera
1.Open Camera Settings and go to the Expert tab.
2.Check Keep camera stream and profile settings.
3.Apply changes.
NOTES:
•This setting is not available for RTSP/HTTP streams.
•Enabling this flag means FPS and image quality settings in the recording schedule will be ignored.
To disable automatic optimization for all cameras
It is possible to do this during the Initial Site Configuration.
Later, it can be done as follows:
Desktop Client
1.Open Main Menu and go to Site Administration > General tab.
2.Uncheck the Allow Site to optimize device settings checkbox.
3.Apply changes.
NOTE: For each camera in your Site, use the web page to set desired image settings.
1.Open Settings > Site Administration > General tab.
2.Unheck the Allow Site to optimize device settings checkbox.
3.Apply changes.
